From: Influence of ejaculation frequency on seminal parameters
The intra- and inter individual variation of the functional sperm parameters. Distribution of functional parameters (DNA fragmentation index, mitochondrial membrane potential, plasma membrane integrity, reactive oxygen species) during the daily ejaculation period. n = 6 individuals (A-F) for each parameter (DFI: DNA Fragmentation Index, MMP: Mitochondrial Membrane Potential, membrane integrity percent, and the production of intracellular ROS: Reactive Oxygen Species)
